    • A ring linkage is hereby disclosed that is comprised of at least six links, each link having at least two pivots located proximate to their ends, said links being arranged in a loop whereby each link is pivotally attached via its end pivots to two neighboring links. The motion of the linkage is synchronized by a multiplicity of mechanical elements that serve to synchronize the relative rotation of the links in the assembly such that when a given link rotates by an angle, every second link rotates by the same angle. These synchronizing elements may be either gears, cables or belts, thus the relative angle between the every second link in the ring linkage (as defined by lines passing through their respective end pivots) remains constant and unchanging even as the position of the linkage is changed.
    • 因此,公开了由至少六个连杆构成的环形连杆,每个连杆具有至少两个位于其端部附近的枢轴,所述连杆被布置成环形,由此每个连杆经由其端部枢轴枢转地连接到两个相邻的连杆。 连杆的运动通过多个机械元件同步,这些机械元件用于使组件中的连杆的相对旋转同步,使得当给定的连杆旋转一个角度时,每个第二连杆以相同的角度旋转。 这些同步元件可以是齿轮,电缆或皮带,因此,环形连杆机构中的每个第二连杆件之间的相对角度(由通过它们各自的端部枢轴的线限定)保持恒定且不变,即使连杆的位置改变 。

    • A loop-assembly is disclosed which is comprised of at least three scissors-pairs, at least two of the pairs comprising:two essentially identical rigid angulated strut elements each having a central and two terminal pivot points with centers which do not lie in a straight line, each strut being pivotally joined to the other of its pair by their central pivot points,each pair being pivotally joined by two terminal pivot points to two terminal pivot points of another pair in that,(a) the terminal pivot points of each of the scissors-pairs are pivotally joined to the terminal pivot points of the adjacent pair such that both scissors-pairs lie essentially in the same plane, or(b) the terminal pivot points of a scissors-pair are each pivotally joined to a hub element which is small in diameter relative to the length of a strut element, and these hub elements are in turn joined to the terminal pivot points of another scissors-pair, such that the plane that one scissors-pair lies in forms an angle with the plane that the other scissors-pair lies in, the axes passing through the pivot points of one of the scissors-pair not being parallel to the axes of the other scissors-pair,where a closed loop-assembly is thus formed of scissors-pairs, and this loop-assembly can freely fold and unfold without bending or distortion of any of its elements, anda line that intersects and is perpendicular to the axes of any two terminal pivot points is non-parallel with at least two other similarly formed lines in the assembly,the angles formed between said lines remaining constant as the loop-assembly is folded and unfolded.
    • 公开了一种环组件,其由至少三个剪刀对构成,至少两个对包括:两个基本上相同的刚性角撑杆元件,每个具有中心和两个终端枢轴点,其中心不位于直线 每个支柱通过它们的中心枢转点枢转地连接到另一对支柱,每对支撑件通过两个端枢点枢转地连接到另一对的两个端枢点,因此,(a) 剪刀对枢转地连接到相邻对的端子枢轴点,使得两个剪刀对基本上位于相同的平面中,或(b)剪刀对的端子枢转点各自枢转地连接到轮毂元件 其直径相对于支柱元件的长度小,并且这些轮毂元件又连接到另一个剪刀对的终端枢轴点,使得一个剪刀对的平面位于形式 与另一个剪刀对所在的平面成一角度,穿过其中一个剪刀对的枢转点的轴线不平行于另一个剪刀对的轴线,由此形成闭环组件 的剪刀对,并且该环组件可以自由地折叠和展开,而不会使其任何元件弯曲或变形,并且与任何两个端子枢轴点的轴线相交并垂直于其的线不与至少两个平行 在组件中的其它类似形成的线,当环组件折叠和展开时,所述线之间形成的角度保持恒定。
